Mongo aggregation with paginated data and totals

Question

I\'ve crawled all over stack overflow, and have not found any info on how to return proper pagination data included in the resultset.

I\'m trying to aggregate some

Answer 1

Did this in two steps instead of one:

// Get the totals
db.mongoAuditEvent.aggregate([{$group: {_id: "$corrId"}}, {$group: {_id: 1, total: {$sum: 1}}}]);

// Get the data
db.mongoAuditEvent.aggregate([
  {$group: {
    _id : "$corrId", 
    currentEvent: {"$last": "$event.status"}, 
    "events": { $push: "$$ROOT"}
  }},
  {$sort: {"events.timestamp": -1} }, // Latest first
  {$skip: 0 },
  {$limit: 10}
], {allowDiskUse: true}).pretty();

I would be very happy if anybody got a better solution to this though.
